Kurumi Kakura is a third-year student at Miyamori Girls' High School in Iwate Prefecture and a supporting character in the manga "Saki". She usually acts in a childish manner but can be critical when provoked. Kurumi is also bit of a snarky character teasing her teammates and opponents alike. She also loves to sit on Shiromi Kosegawa's lap.

Kurumi does not declare riichi during her matches, thus opponents are not able to determine whether she has reached tenpai. Kiyosumi High School's Hisa Takei likens this to the stealth riichi of Tsuruga Academy's Momoko Touyoko.
